wagamama dakedo itoshikute

I read all five volumes of Wagamama dakedo itoshikute by Itsuki Kaname and overall enjoyed it quite a lot. I loved the spaced-out nearly helpless very very pretty seme x very nuturing very capable uke dynamic of the main couple. So cute! I also liked the brothers in volume 4. There's nothing like siblings who only have each other who take that forbidden step for me. XDXD But I was annoyed by the third couple in volume 5. I definitely like to focus on fewer couples/characters rather than more, and I'd rather have more time spent on the two other couples instead of filling the last volume with a new couple. Especially since I didn't care for either characters in the last couple very much. I think it may have been more fun if that couple switched as per sensei's afterward, but otherwise it was too same old same old for me. *shrugs*
